This is unfortunate. I used O.o to implement type-safe lenses in my TypeScript project (https://github.com/wereHamster/avers https://github.com/wereHamster/avers). I always cringe when I see Immutable.js `c.setIn(['some','deeply','nested','field'], x)`, so much opportunity for typos, and no support for refactoring. For a while now I wanted to use proxies, but they are only supported in Firefox, and no timeline when they get to Chrome. I'll have to see what I can use as replacement.
